ESP VOLKSWAGEN EOS 2014 1.G Service Manual

WARNING
Wet brakes or brakes coated with ice or road salt react slower and need longer stopping distances.
x Carefully apply the brakes to test them.
x Always dry brakes and clean off ice and salt coatings with a few cautious brake applications when visibility, weather, road and traffic conditions permit.
WARNING
Driving when the brake booster is not working increases stopping distances and can cause accidents and serious personal injuries.
x Never let the vehicle coast when the engine is switched off.
x If the brake booster is not working (such as when the vehicle is being towed), a lot more pedal force is needed to slow down and stop.
NOTICE
x Never “ride” the brakes by keeping your foot on the brake pedal when you do not want to brake. Constant pressure on the brake pedal can make the brakes overheat. Riding the brakes will substantially reduce braking performance, increase stopping distance, and can cause complete brake system failure.
x Before driving downhill, especially on hills that are long or steep, always reduce speed and shift into lower gear (manual or automatic transmission). This will let the vehicle use engine braking and reduce the load on the brakes. Otherwise, the brake system could overheat and possibly fail. Only use the brakes when you need them to slow the vehicle down more or to stop.
When the front brakes are serviced, you should have the rear brake pads inspected at the same time. The wear of all brake pads should be visually checked regularly. The best way to check for brake pad wear is to have your authorized Volkswagen dealer or authorized Volkswagen Service Facility visually inspect the pads through the openings in the wheel rims or from underneath the vehicle. If necessary, the wheels can be taken off for a more thorough inspection.
Braking assistance systems

Calm and smooth driving
Consistency is more important than speed. The more smoothly you drive, the less fuel the vehicle consumes.
When driving on the highway or freeway, a constant, moderate speed is more efficient and economical than constantly accelerating and braking. Usually you can reach your destination just as quickly by driving at a moderate, but steady speed.
The cruise control system can assist in maintaining a uniform driving style.
Moderate use of extra electrical loads
Comfort inside the vehicle is nice and important, but it is important to use them in an environmentally conscious manner.
Some devices can increase fuel consumption when activated (examples):
x Climate control system (air conditioner): If the air conditioner has to produce starkly contrasting temperatures, it requires a large amount of energy, which is generated by the engine. The temperature in the vehicle should therefore not be extremely different from that of the outside temperature. It may be helpful to ventilate the vehicle before driving and then to drive a short distance with the windows open. After that, switch on the air conditioner with the windows closed. Keep the windows closed when driving at high speeds. Open windows increase fuel consumption.
x Switch off seat heating once it has served its purpose.
x Switch off the rear window defroster as soon as the windows are free of fog and ice.
Additional factors that increase fuel consumption (examples):
x Malfunctioning engine control.
x Driving in the mountains.
x Towing a trailer.
NOTICE
Never let the vehicle coast or roll down a hill in Neutral (N), especially when the engine is not running. The transmission will not be lubricated and will be damaged.

WARNING
Rear Assist technology cannot overcome the laws of physics and the limits of the system. Careless or unintentional use of Rear Assist may result in accidents and severe injuries.
x Always adjust your speed and driving style to road, traffic, weather, and visibility conditions.
x Always keep an eye on the parking direction and the vehicle surroundings. The front of the vehicle swings out more than the rear of the vehicle.
x Never pay so much attention to the graphics shown on the screen that you fail to notice what is going on around you.
x Always watch for people, especially small children, animals, and objects, because the camera may not always be able to detect them.
x The system may not be able to clearly show everything behind the vehicle.
x Use Rear Assist only when the luggage compartment lid is completely closed.
NOTICE
x The camera shows only two-dimensional images on the screen. Due to the lack of depth of field, it may be difficult or impossible to identify protruding objects or recesses in the road, for example.
x Things like thin rods, fences, posts, and trees may not be detected by the camera and could damage the vehicle.
Operation

Fig. 140 In the luggage compartment lid: Location of the Rear Assist camera.

WARNING
x Opening and closing the luggage compartment lid and the CSC roof can cause serious injuries if someone gets in the way of moving parts. The rear lid assist system is no substitute for careful and attentive driving. It is the driver's responsibility to make sure that nobody is in the way when opening or closing the luggage compartment lid, particularly when putting the CSC roof up or down.
x If the opening or closing process is interrupted or the hydraulic pump overheats, the CSC roof will automatically lower itself into a balanced position after a while (may take up to 8 minutes).
NOTICE
x Things like trailer draw bars, thin rods, fences, trees, narrow painted vertical poles, posts, or a luggage compartment lid that is opening may not be detected by the Park Distance Control sensors and could damage the vehicle.
x If you continue driving closer to an object that the Park Distance Control has already detected and reported, the object may disappear from the sensor range and may no longer be detected. This is especially true for low or high objects. The system will no longer sound warnings about these objects. Ignoring signals from the Park Distance Control system could result in serious damage to the vehicle.
x The sensors in the bumper can be damaged or become misaligned in low speed impacts and parking maneuvers. Damaged or misaligned sensors cannot accurately detect or report objects that might be within range of the PDC system.
x To help make sure that the system works properly, always keep the sensors in the bumpers clean and free of snow and ice; do not cover the sensors with stickers or other objects.
x When cleaning the sensors with power washers or steam cleaners, only spray the sensors directly for a very short time, and always keep the washer nozzle at least 4 inches (10 cm) from the sensors.
x Noise from rough roads, cobblestones, other vehicles and the surrounding area, for example, can prevent the Park Distance Control system from accurately detecting and reporting people and objects that may be within range of the system sensors.
x Aftermarket components such as bicycle racks can impair the function of the Park Distance Control system.
NOTICE
x Rear lid assist does not detect obstacles above the rear bumper. For this reason, always check to make sure there is enough room behind the vehicle before opening or closing the CSC roof.
x When the CSC roof is opening or closing, the luggage compartment lid lowers and covers the Park Distance Control sensors. The sensors cannot detect people or things that are moving behind the vehicle within range of the luggage compartment lid or that were not there before the lid began to descend.
x Rear lid assist only checks the area behind the vehicle for obstacles at the start of CSC roof operation, when the roof is still completely closed or open. If roof operation is interrupted, the area behind the vehicle will not be checked a second time when roof operation starts again.
x You can damage the vehicle if rear lid assist detects an obstacle and stops CSC roof operation, and you continue to operate the switch to open or close the roof.
Volkswagen recommends practicing with the Park Distance Control system in a location or parking space with no traffic in order to become familiar with the system and how it works.

Rear lid assist during opening and closing the CSC roof
Before the CSC roof opens or closes, the rear lid assist system uses the PDC sensors to check that there is enough room behind the vehicle for the rear lid to swing out past the rear bumper.
x If an obstacle is detected, roof operation stops. Unlike the Park Distance Control system, rear lid assist has no acoustical alert signal. Remove any obstacles behind the vehicle or move the vehicle forward so that there is enough room for the luggage compartment lid to swing out.
x If you operate the CSC roof lever again after roof has automatically stopped (because rear lid assist has detected an obstacle), roof operation will start again after a few seconds. The CSC roof will not stop again automatically if an obstacle is detected a second time. Instead, a warning will appear in the instrument cluster display.
x Because the rear lid assist system uses the PDC sensors, its operation depends on whether or not the PDC system is working properly. PDC is working properly if the warning chime sounds when you shift into Reverse.
Muting the Park Distance Control volume
You can mute the PDC beeping signals by tapping the + function key on the Radio or Navigation system screen (if applicable). Tap the function key again to reactivate the acoustic signals.
Switching Park Distance Control back on after it was switched off reactivates the volume. System malfunction warning signals cannot be switched off.
WARNING
Never rely completely on the PDC for information about people and objects that might be in the way of the vehicle and could be struck by the vehicle causing serious personal injury.
x The PDC sensors have blind spots where they cannot detect people or objects.
x Always watch for people, especially small children and animals, because the sensors may not always be able to detect them.
If you hear a long beep lasting about 3 seconds when you first turn PDC on, this means there is a malfunction in the Park Distance Control system. Switch off the Park Distance Control system with the button and have it immediately checked by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
Rear lid assist can be deactivated by an authorized Volkswagen dealership or authorized Volkswagen Service Facility. If this is done, Park Distance Control still works and will give an acoustic warning if the CSC roof is opened or closed while the vehicle is in Reverse. The signal sounds as soon as the luggage compartment lid swings into the area scanned by the PDC sensors.

Air vents
To help ensure sufficient heating, cooling and ventilation in the passenger compartment, never close
the air vents completely ⇒ fig. 146 (1).
x To open and close the air vents, turn the respective thumbwheel (magnified view) in the desired direction. When the thumbwheel is turned all the way toward the O, the air vent is closed.
x Use the lever on the vent grille to adjust the airflow direction.
Additional, non-adjustable air vents are located in the front door pillars and the instrument panel (2), in the footwells, as well as in the rear area of the passenger compartment.
NOTICE
Do not place food, medications, or other heat-sensitive things in front of the air vents. Food, medications, and other things that are sensitive to heat or cold can be damaged or made unusable by the air flow from the vents.
Air recirculation

WARNING
Even if empty, portable fuel containers can leak and cause a fire and serious personal injuries, especially in a crash.
x For your safety, we strongly recommend that you do not travel with a portable fuel container in your vehicle.
x If, under exceptional circumstances, you must transport a portable fuel container, please observe the following:
– Never fill a portable fuel container while it is anywhere in or on the vehicle (for example, in the luggage compartment or on top of the luggage compartment lid). Static electricity can build up while filling and can ignite fuel vapors, causing a fire.
– Always place a portable fuel container on the ground before filling. Never spill fuel inside the vehicle or luggage compartment. Fuel vapors are highly flammable.
– Always keep the filler nozzle completely inside the portable container before and during filling.
– If filling a portable container made of metal, the filler nozzle must always be in contact with the container. This will help prevent static electricity from discharging and causing a fire.
– Always observe local and state or provincial laws about the use, storage, and transportation of portable fuel containers.
– Make certain that the portable fuel container meets industry standards, such as ANSI/ASTM F852-86.
NOTICE
x Remove fuel spills from the vehicle immediately to help prevent damage to the paint, tires, and wheel housings.
x Refueling with gasoline when your vehicle has a diesel engine or refueling with diesel fuel when your vehicle has a gasoline engine can cause very serious and expensive engine and fuel system damage that is not covered by any Volkswagen Limited Warranty.
x If you put any amount of incorrect fuel in the fuel tank, do not start the engine under any circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance. These fuels contain substances that can severely damage the fuel system and the engine if the engine is started.
Fuels can pollute the environment. Spilled fuel must be collected and disposed of properly, following all applicable environmental regulations.

Octane rating
Octane rating indicates a gasoline's ability to resist engine-damaging “knock” caused by pre-ignition. Using the correct grade of gasoline is very important to help prevent engine damage and loss of engine performance.
The recommended gasoline octane rating for your engine is listed on a label inside of the fuel filler flap. This rating may be specified according to AKI (CLC) or RON (ROZ) standards.
If unleaded Premium grade gasoline is specified for your vehicle, then Volkswagen recommends using TOP TIER Detergent Gasoline with a minimum octane rating of 91 AKI (95 RON). For more information on TOP TIER Detergent Gasoline, please go to the official Web site, http://www.toptiergas.com.
The gasoline grades most commonly sold in the United States and Canada have the following octane ratings, which can usually be found on the filler pump:
x Premium grade: 91 to 96 AKI
x Regular grade: 87 to 90 AKI
Unleaded gasoline
Unleaded gasoline is available throughout the USA and Canada. Volkswagen recommends that you do not take your vehicle to places where unleaded gasoline may not be available.
Gasoline containing alcohol or MTBE
You may use unleaded gasoline blended with alcohol or MTBE (methyl tertiary butyl ether), commonly referred to as oxygenated fuels, if the blended mixture meets the following criteria:
Blends of gasoline and methanol (wood alcohol or methyl alcohol):
x Anti-Knock Index (AKI) must be 87 or higher.
x Blend must contain no more than 3% methanol.
x Blend must contain more than 2% co-solvents.
Blends of gasoline and ethanol (grain alcohol or ethyl alcohol):
x Anti-Knock Index (AKI) must be 87 or higher.
x Blend must contain no more than 10% ethanol.
Blends of gasoline and MTBE:
x Anti-Knock Index (AKI) must be 87 or higher.
x Blend must contain no more than 15% MTBE.
Seasonally adjusted gasoline
Many fuels are blended especially for winter or summer conditions. When seasons change, Volkswagen suggests that you buy fuel at busy stations where the seasonal adjustment is more likely to be made earlier.
WARNING
Starting fluids can explode and cause a run-away vehicle condition.
x Never use starting assist fluids.
NOTICE
x Never use fuel with an octane rating lower than 87 AKI/91 RON. Using lower octane fuel may cause expensive engine damage.
x Never use leaded gasoline! Leaded gasoline will severely damage your vehicle's catalytic converter.

x Methanol-blended fuels that do not meet the criteria listed above may cause corrosion and may damage plastic and rubber parts in the fuel system.
x Never use fuels that contain lead or other metals (check listing on the fuel pump). Even lead replacement gasoline (LRP fuels) contain metallic additives in high concentrations. They can damage the engine.
x Do not use fuels that fail to meet the criteria above, or with contents that cannot be identified.
x If you cannot tell whether a particular fuel blend meets the criteria above, ask your service station or its fuel supplier. If you notice a loss of fuel economy or drivability and performance problems using one of these fuel blends, we recommend that you switch to unblended fuel.
x Using fuels that are different from those specified above can damage your vehicle's engine and fuel system and cause performance problems.
x Damage to the engine and fuel system and performance problems caused by using fuels that are different from those specified above or by using “starting assist fluids” are not the responsibility of Volkswagen and are not covered under the Emission warranties or any other Volkswagen Limited Warranty.
Even a single tank full of leaded fuel can do major damage to the catalytic converter and degrade its effectiveness in reducing polluting emissions.
If you notice a loss of fuel economy or drivability and performance problems using one of these fuel blends, we recommend that you switch to unblended fuel. Never use fuel line antifreeze offered for gasoline engines.
Gasoline additives

WARNING
High voltage systems in the engine compartment can cause electrical shocks or even electrocution, severe burns, other serious injuries, and even death!
x Never short-circuit the electrical system. Be especially careful when using jumper cables. The vehicle's battery could explode!
x To reduce the risk of electrical shock and personal injury while the engine is running or being started:
– Never touch ignition cables. Never touch other components of the high voltage electronic ignition system.

x Never reach into the area around or touch the radiator fan. Contact with the blades can cause serious personal injury. Always remember that the radiator fan is temperature-controlled and can come on suddenly even when the engine has been switched off for a while and the key has been removed from the ignition.
x If you have to perform a check or repair when the engine is running, there are more risks from the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from the high-voltage ignition system. Always use extreme care.
– Always make sure that jewelry, loose clothing and long hair do not get caught in rotating engine parts. Before starting any work remove your jewelry, take off your necktie, tie back and cover your hair, and do not wear clothing that can hang down and get caught in moving engine parts.
– Always use extreme caution if the accelerator pedal has to be depressed to perform a check. The vehicle will start to move even if the parking brake is on.
x Never leave any objects in the engine compartment, for example cleaning rags and tools. Objects left behind can cause malfunctions, engine damage, and even fires.
WARNING
Operating fluids and some materials in the engine compartment can catch fire easily, causing burns and other serious personal injuries!
x Never smoke near the engine compartment.
x Never work next to open flames or sparks.
x Never pour or spill operating fluids or other flammable liquids on the engine. These fluids can ignite on hot engine parts and cause injuries.
x If work on the fuel system or the electrical system is necessary:
– Always disconnect the 12 Volt vehicle battery. Make sure the vehicle is unlocked when you disconnect the battery, or the alarm will go off. Never touch the electrical wiring of the ignition system.
– Never work near heaters, water heaters, or other open flames.
x Always have a functional, approved fire extinguisher nearby.
